Based on VSEPR theory, which of the following sequences correctly represents the increasing order of bond angles for the given molecules?

Step-by-step solution

In H ₂ S , the central atom sulfur is sp^3 hybridized and has two lone pairs. Due to strong lone pair-lone pair repulsions, the bond angle decreases significantly to approximately 92^ . In CH ₄ , the central atom carbon is sp^3 hybridized with no lone pairs. The geometry is perfectly tetrahedral with a bond angle of 109.5^ . In BF ₃ , the central atom boron is sp^2 hybridized with no lone pairs. The geometry is trigonal planar with a bond angle of 120^ . In BeF ₂ , the central atom beryllium is sp hybridized with n
